Acrocordia Lichen

This page provides information about lichens belonging to the genus Acrocordia, with a focus on several species, including Acrocordia gemmata, Acrocordia conoidea, Acrocordia macrospora, Acrocordia salweyi, and Acrocordia cavata.

Considerations for Pets

  • The crustose body type, observed in species like Acrocordia salweyi may potentially present a ingestion risk to pets, especially curious ones.

Scientific Classification

  • Kingdom: Fungi
  • Family: Monoblastiaceae
  • Genus: Acrocordia A. Massal.

Nomenclature

  • Acrocordia gemmata (Ach.) A. Massal. is also known by the common names "acrocordia lichen" and "bud-bearing shell lichen."
  • Synonyms for Acrocordia gemmata include:
    • Arthopyrenia alba (Schrader) Zahlbr.
    • Arthopyrenia gemmata (Ach.) A. Massal.
    • Arthopyrenia sphaeroides (Wallr.)
    • Lichen gemmatus Ach.

Morphology and Growth

  • Acrocordia lichens are described as having a "crustose" body type.
  • Acrocordia macrospora has black dots, known as perithecia.

Distribution and Habitat

  • Acrocordia gemmata has been found in:
    • Europe (e.g., Portugal, Algarve region)
    • Britain and Ireland
    • Turkey (on Fagus sp.)
    • Dorset
  • Acrocordia conoidea is found in the Greater Sonoran Desert region.

Ecological Role

  • Acrocordia species are lichens, which are composite organisms consisting of a fungus and an alga or cyanobacterium.
  • Some Acrocordia species, like Acrocordia gemmata, are considered vulnerable in certain regions.

Quirky Facts

  • Acrocordia salweyi has "empty pits with a black ring," a distinctive feature.

Interactions with Other Organisms

  • Acrocordia gemmata has been found growing on Fagus species (beech trees).
  • Some species of Acrocordia participate in gas exchange with other endolithic lichens.
